3 Claims.

An object of my invention is to provide a simple, durable and inexpensive window construction of combination character wherein a pair of sashes are both slidably and hingedly mounted.

Still another object is to provide an automatic double hung sliding sash window with means for hinging the sashes so that the entire window can be opened in the manner of a Casement or Queen Anne sash for better ventilation and the sashes can be readily manipulated to positions greatly facilitating washing of the windows or application or removal of window screens and storm sashes.

With these and other objects in View my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of a window construction embodying my invention.

Figure 2 is an enlarged horizontal sectional view on the line 2-2 of Figure 1.

Figure 3 is a sectional view on the line 3-3 of Figure 2 showing details of construction; and

Figure 4 is a sectional view on the line 4-4 of Figure 1 on an additionally enlarged scale showing a detachable connection of the invention.

On the accompanying drawing, I have used the reference character A to indicate an upper sash and B a lower sash. These sashes are of the ordinary construction having rails I0 and stiles I2 with the exception that the stiles are cut so that each sash has additional stile parts I2a and I2b. Each sash proper A and B is hingedly connected as by butt hinges I4 with the stile parts I2a and detachably secured to the stile parts |2b by spring plungers I6 and hooks I8.

A socket element 20, as shown in Figure 4, is embedded as by screw threading, in the stile part I2b (see Figure 4) while eyes 22 are provided in this stile part for the hooks I8 to engage.

The plunger I6 is urged in a connecting direction by a spring 24, a knob 26 being provided for convenience in retracting the plunger.

The stile parts I 2a and I2b are slidably and non-rotatably associated with the window frame, indicated generally at C, by the following described construction:

The stile parts I2a and I2b are grooved as indicated at 28 to receive slotted tubular or channel shaped elements 30. Headed elements such as round head screws 32 are associated with the window frame in such manner that they extend through the slots of the tubular elements 30 and have their heads within the elements.

The sashes A and B are counter-balanced preferably in the following manner:

For the lower sash B, a single counter-weight 34 is provided. A sash cord 36 has one end connected therewith, extends over a pulley 38 and has its other end connected as to an eye 40 formed in the upper end of the tubular gu1de element 30. The upper sash A is counter-balanced by a pair of weights 42 and sash cords 44 connected in a similar manner, one with each stile part I2a and I2b of the upper sash A.

Practical operation In the operation of my device the sashes are normally closed as shown by solid lines in Figure 2 and operate in the ordinary manner of double hung, sliding sashes. When it is desired to open the sash, however, for any of the reasons specied in my objects or for any other reason the hooks I8 can be unhooked and the spring plungers retracted, whereupon the sashes can be swung to any position desired, for instance, as shown by dotted lines in Figure 2 or as clearly illustrated in Figure 1.

The stile part I2b of the lower sash B, since it is not counter-balanced, will remain at the lower end of its groove in the window frame. The other stile part I2b, being counter-balanced, will remain at the upper end of its groove. When the sashes proper A and B, however, are secured to the stile parts I'Zb these parts will move with the sashes during sliding movement in the ordinary manner.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:

1. In a window construction, a sliding sash including wood rails and Stiles, said stiles being vertically sawed in two, the two parts thereof at one side of said sash being hinged together and the two parts thereof at the other side of the sash being detachably secured together, the outer edges of the outer parts of said stiles being vertically grooved, metallic slotted tubular liners in said grooves and means for retaining the outer parts of each stile slidably but non-removably associated with a window frame comprising a plurality of vertically spaced screws in the side jambs of the window frame having their heads within said tubular liners and their Shanks extending through the slots thereof.

2. In a window construction, a sliding sash including rails and stiles, each of said stiles comprising two parts, the two parts thereof at one side of said sash being hinged together and the two parts thereof at the other side of said sash being detachably secured together, and means for retaining the outer parts of each stile slidably but non-removably associated with a Window frame, said means comprising slotted tubular elements of less width than the thickness of said rst parts, said rst parts being vertically grooved, said slotted tubular elements being received in and lining said grooves substantially throughout the lengths thereof and headed elements extending from the slots thereof with ceived in said grooves, and headed elements extending through the slots thereof with their heads within the tubular elements, said headed elements being secured at spaced intervals to the side jambs of a window frame.
